To w/l 0m. item 3, con 0cm:

Be it known that l, Evnar Koiuio, a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota,have invented certain newand useful Improvements in Vehicle Wheels, ofwhich the following is a specification.

This invention relates to improvements in vehicle wheels and moreparticularly to demountable rims therefor whereby to facilitate"theapplication and removal of pneumatic tires when necessary. Novel meansfor retaining the rim in operative position are also provided.Simplicity in construction and efficiency in operation are objectsattained.

With the foregoing and other objects in view the invention consistsinthe combination and arrangement of partsto be hereinafter fullydescribed, pointed out in the appendedclairns and illustrated in theaccompanying drawing which forms apart of this application and in which-Fig. 1 is a section through a vehicle wheel constructed according to mypresent invention.

Fig. 2 is an edge view of the sectional rim, its component parts beingseparated.

Fig. 3 is a side view of Fig. 1.

Fig. 4 is a side View of the vehicle wheel,-

Fig. 5 isa fragmentary view of Fig. 1 with one of the relatively movableparts in an altered position.

Like reference characters denote corresponding parts throughout theseveral views.

The reference numeral 1 denotes the felly of the wheel 2, and said fellyis formed along one edge with a plurality of spaced bevelled portions 3or, if preferred, this bevel. may be made continuous. My rim propercomprises two telescoping portions 4, 5, it being a circumferentiallysplit rim and each of its component portions is formed with anupstanding side portion 5 and with an outwardly turned flange 6, saidrim portions being'formcd also with the grooves 7 which, in thetelescoped position of said portions, form a perforation for the tirevalve.

The rim portion 4 and its flange 6 are formed with a plurality of ears 8to, which the bifurcated sides 9 of the substantially U-shaped yokes 10are pivotally secured by the bolts 11, said yokes 10 being formed withthe heels 12. The size or width of the yokes 10 is such that when therim sections are telescoped said yokes will snugly span or straddle thesections, the sides of the ill-shaped yokes being disposed against thesides of the rimsections immediately adjacent the outwardly turnedflanges 6 and serving to positively retain the rim sections intelescoped position.

1' The "rim is applied to the bevelledsidc of the felly'and forced uponthe felly, the

rim sections being telescoperi at the time and engaged b the rim yokeswhich rest directly upon t e felly, the base of the heel portionsresting upon the bevelled portion 3 of the felly. A plurality of bolts13 extend through the felly, one for each rim yoke, and the rim is soapplied to the folly that the yokes are disposed in alignment with thesaid bolts. Each bolt 13 carries a' wedge block 14--:having a bevelled,end 15 which end, in one position of the block-upon the bolt, isadapted for engagement with the heel 12 of the rim yoke 10. After therim has been applied to the felly the wedge blocks 14: are movedupon'the bolts 13 as a pivot until they engage with the heels 12. Theblocks 14 are then tightened against the heels 12 and the felly by meansof the nuts 16 on the bolts 13 and the rim'thus securely fastened inposition upon the felly. Thetire 17 is applied to and removed from therim in the usual manner, the clencher beads 18 being gripped by the rim.

To remove the rim it is only necessary to loosen the nuts 16, move theblocks 14 out of engagement with the rim yokes and the rim can be movedmanually off the folly. When the rim is off the wheel the rim yokes canbe dropped to the position shown in Fig. 5 and the'rim sections spreadapart and the tire removed.

What is claimed is 1. In a vehicle wheel, a fellv having onev bevellededge, a rim, rim yolres pivotally posal upon the said felly, said rimyokes beingadaptod to snugly span the rim, heels integral with said rimyokes for engage merit with the bevelled portions of said folly, andadjustable means carried b said till and adapted for disposal upon thesaid felly, a portion of the base of said rim restcarried by said rimand adapted for disll 'ing upon the bevelled portion of saidfelly,

upon the bevelled portions of the felly, bolts yokes for binding themfirmly' to carried by said felly, wedge blocks arranged upon said boltsfor engagement with the said heels, and nuts upon said bolts foroperative engagement with said wedge blocks.

In testimony that I claim the foregoing as my own I have hereto afiixedmy 'signature in the presence of two subscribing witnesses.
